UNITED STATES A'rnn'r QFFICE,
RUDOLPH DHEUREUSE, OF new YORK, N. Y.
IMPROVEMENT IN PROCESSES OF PREPARING MASH.
Specification forming part of Letters Patent N0. 19! ,94 2, dated June 12, 1877; application filed August 15, 1876.
To all whom it may concern: Beit known that I, RUDOLPH DHEUREUSE,
. of the city, county, and State of New York, have invented new and useful Improvements in Process for Treating Malt, either alone or mixed with starchy matters, so as to produce a wort or sweet-mash, for brewing, distilling,
perature so as to injure the diastase of the malt.
The usual mode of producing a wort or sweet-mash from malt, either alone or mixed with starchymaterials, is to mixthe malt with water, by some sort of mixer, or to mix the previously-prepared starchy niateriahin a wet state, with the malt, which is commonly done in an open or covered mash-tun at a tempera ture of 140 to 175 Fahrenheit, with or withoutfurther stirring, and the converting action of the diastase of the malt upon the starch of the material is allowed to run its course, requiriug generally from three to six hours to be completed, as far as in this manner it can be accomplished at the ordinary atmospheric pressure.
The treatment in vessels under ordinary atmospheric pressure is defective, for the reason that the saccharifyin g conversion of the starch in the material is slow and imperfect, the diastase not penetrating to a considerable proportion of the starchy particles, thereby occasioning loss; and the use of steam, as ordinarily employed in the process, at high or low pressure, is objectionable, for the reason that the heat therefrom, above 175 Fahrenheit, destroys the diastase, the acting principle of the malt.
My invention is designed to overcome these defects, by subjecting the malt, or the malt and unmalted material, to a treatment in which is employed a temperature that will not injure the diastase of the malt, say a temperature of 140 to 175 Fahrenheit, or thereabout,
, treated, as may be deemed best.
and in which are obtained,'at the same time,
the benefits of a high pressure without such degree of heat as would injure the diastase of the malt.
I will now proceed to describe my process of mashing. The vessel or tank (which may be similar to that described in the patent of J.
dHeureuse, April 25, 1876, No. 176,631, and provided with steam-jacket, or its equivalent, to heat the contents, with a false perforated bottom or plate to drain the liquid, gate for the residue, thermometer, and such other appliauces as the nature of the material may require, or any other suitably-constructed vessel will answer) is charged with water of the required temperature, which should not exceed 175 Fahrenheit, although it may be considerably below that-for instance, a good and a mean temperature is 150 Fahrenheit-and with the malt, which is not necessarily crushed and the pressure prod need within so as not to raise the temperature of the mash to a degree which would injure the malt, although at the termination of the accomplished saccharification, when the diastase has done its work, the mash may be raised to the boiling-point without injury to the product.
The pressure may be produced by compressed air, carbonic-acid gas, or by any other gas which will not injure the material under treatment, or it may be by means of hydraulic or hydrostatic pressure, or by admission of steam above the surface of the material treated, as the heat acts downward but slightly. Under a pressure maintained at twenty-five pounds per inch and upward, the conversion of the starch takes place rapidly,-and the contents of the tank may then be discharged, drained, or otherwise The temperature can always be kept up to that required, while the pressure may be raised to any required degree which the vessel will bear, and which the pumps or other compressing devices are capable of producing.
I thus avail myself of the benefits of a high pressure without such degree of heat as would injure the diastase of the malt, so that this diastase is made to quickly penetrateand convert all starch into dextrine and sugar, thereby producing, in less time, more extractive matter from the malt, grain, &c.,. equivalentto aiplropvontionalliy larger yield of alcohol than. by the old modes.
I have just described the process as carried on upon malt alone. I will now proceed to describe it as worked upon the unmalted material. It is like the former in many" respects.
The un malted starchy material (grain, meal, &c.) is first softened by scalding, steaming, or other known and" convenient modes, to open theparticles of starch for the subsequent action. of the grain may be done'in th'evessel already described for mashing malt, and which is used for the subsequent steps of the process. If it be not so done, this preparatory mashing is done in any other suitable vessel, after which it is charged into-the tank, above described, for mashing malt, and" while ata temperature of about 150 to 175 Fahrenheit, a proportion of malt, (generally one-fourth to one-twentieth of the unma'l'ted material,) or an equivalent proportion of wort or extract of malt, is addedthereto the tank is closed, the contents thoroughly mixed, and a pressure is applied to the same by compressed air or gases, by admission ofliquids' underpressure, or bydire'ct admission of steam above the surface of the contents, as described for malt alone. The
saccharifica't'ion or. conversion of the starch into dextrine and sugar takes place rapidly and completely, and whenzaccomplish'ed the". contents of the tank are discharged, or? other.- Wise treated.
It will be understood that the mode by" which the pressure is produced, for" the pur: poses described, will depend, in each case, upon facilities which favor one mode or another.
Hops may be added to the mash, from malt alone or mixed with starchy or saccharine .materials, at thebeginning or at some other time of the operation, and either the whole amount This preparatory softening or mashing fivepounds per inch as a good one to be used in this. process, yet it is obvious that it may be sel without loss of volatile parts of the hops.
As the wort obtained by the process described will requiregas a rule, less boiling than that produced in the ordinary modes, (with- .out pressure), this. simultaneous extraction of the hops, at the time of mashing, will insure advantages of various kinds.
While I have stated a pressure of twentymore or less, as the condition of the treatment requires.
I do notv claim, broadly, the treatment. of :malt,.either' alone or mixed'with starchy or saccharine material, in an open nor in a close chamber, and un'der'za; high pressureof steam,
or: with or withouttheuse'of acids, regardless of the temperature"; but.
Having described. my invention, what. I
claim is' Theprocess ofcpreparingmash.from' mixtures of malt, wort, or extract ofmalt and unmy own I affix my signature in presenceof two witnesses.
